Spinner Erin Osborne was devastating for the Melb Stars in the WBBL win over Brisbane Heat.

The Melbourne Stars kept their WBBL finals aspirations alive after spinning their way to an upset six-wicket victory over the in-form Brisbane Heat at Mackay.

The Stars set up their third victory of the season with a wonderful performance with the ball, primarily from their tweakers, restricting the Heat to a paltry 8-93 before comfortably chasing the small target down in 17.2 overs.

Offspinner Erin Osborne was the chief destroyer on Saturday night with the ball taking 4-20, including gun opener Beth Mooney, who was bowled off the second ball of the night.

Wrist spinners Alana King and Kristen Beams combined to snare 3-19 from eight bamboozling overs.

The Heat slumped from 3-8 to 5-29 and things weren't looking much better when they were still reeling at 6-40 in the 13th before Southern Stars allrounder Jess Jonassen produced a fine rearguard run-a-ball 46 in difficult batting conditions.

Joanssen also proved more than handy with the ball, finishing with 1-6 off three overs, and Sammy-Jo Johnson took 2-26 but Brisbane's total always looked light on.

After Lizelle Lee fell for nine, fellow South African Mignon du Preez held the Stars' run chase together, top-scoring with an unbeaten 36 off 34 deliveries to slam shut the Heat's five-match winning streak.

It was also sweet and swift revenge for Friday night's loss.
